Abstract Additive manufacturing (AM), acclaimed as the most representative manufacturing technology in the “third
industrial revolution”, is a manufacturing process where material is added through deposition or melting in a layer-by-layer
fashion. This special manufacturing process makes the fabrication of the structures with complex shapes and geometrical
features possible. AM has been the subject of several studies, the breakthrough in manufacturing is yet to be followed by a
breakthrough in designing process. Topology optimization (TO) is a powerful free-form design tool that couples finite element
analysis with mathematical programming to systematically design for engineering problems. It does not require a preestablished
design and is capable of giving some new, sometime unanticipated, design ideas to designers. In this paper, we
seek to leverage the full potential of this burgeoning manufacturing technology by reviewing the new design algorithms
based on topology optimization.
